Satellite Eyes

Satellite Eyes is a simple Mac app that automatically changes your desktop
wallpaper to the satellite view of where you are, right now.

The app sits quietly in the menu bar at the top of your screen. Pull your
laptop out somewhere new, and your desktop will automatically change to the
view from overhead.

It features a number of different map styles, ranging from aerial
photography to abstract watercolors. And if you have multiple monitors, it
will take advantage of the full width, spanning images across them.
